General Sensory Afferent Systems (GSA) Flashcards
Autonomous Zones: bottom of the paw (thoracic limb)
Median Nerve
___________: how nervous system receives information about the external environment
Enteroception: how nervous system receives information about the external environment
Autonomous Zones: Inner aspect of the pinna
Facial Nerve
Autonomous Zones: Inguinal area
Genitofemoral Nerve
Autonomous Zones: Shoulder area
Axillary Nerve
Autonomous Zones: Medial aspect of the thigh
Saphenous Nerve
___________: same sensory information is sent to multiple destinations for different purposes
Divergence: same sensory information is sent to multiple destinations for different purposes
__________: information traveling to the nervous system retains spacial relationships of the receptors in the periphery
Somatotopy: information traveling to the nervous system retains spacial relationships of the receptors in the periphery
__________: determine how sensitive an area is
Receptive Fields: determine how sensitive an area is
__________: sensory from skin and skeletal muscle
General Somatic Afferent (GSA): sensory from skin and skeletal muscle
____________: how nerveous system recieves information about the position and movement of the body
Proprioception: how nerveous system recieves information about the position and movement of the body
Explain the Somatosensory Pathway
Stimulus to Primary Neuron
Primary Neuron to Secondary Neuron
Secondary Neuron to Contralateral Thalamus
Somatosensory inputs go to the (ipsilateral/contralateral) thalamus/cortex
Somatosensory inputs go to the (ipsilateral/contralateral) thalamus/cortex
Afferent information can go where
Cortex
Cerebellum (Specific Spinal Cord Segments)
ARAS
Autonomous Zones: Mandible and back of the ear
Mandibular Branch of Trigeminal Nerve
